Justice of the peace

• 1. Introduction

  ›

  The justice of the peace is one of the oldest judicial offices in the English-speaking world, tracing its roots to a royal commission issued in 1195 by Richard I of England. That commission sent certain knights into unruly areas to preserve what the Crown called the "King's peace." Eight centuries later, that same basic idea still shapes how minor courts operate across dozens of countries.

  What does it actually mean to be a justice of the peace today? The answer depends entirely on where you live. In one country, a JP might preside over a criminal court, send someone to prison, and set bail. In another, the title is purely honorary, a mark of community standing with no judicial function at all. And in some places, like Ireland, the position was abolished outright in the 1920s and replaced with something entirely different.

  This documentary follows the JP from its medieval English origins through its transplantation to the American colonies, Australia, Canada, and dozens of other jurisdictions worldwide. The story involves unpaid volunteers, landmark US Supreme Court cases, the first women ever appointed to the bench, and a small Pacific island kingdom that only introduced the office in 2014.

• 2. Medieval Roots

  ›

  Richard I's 1195 knights were called "keepers of the peace," responsible to the king for upholding the law in difficult regions. This was a practical solution to a practical problem: the Crown could not be everywhere, so trusted local figures were empowered to act in its name.

  The Justice of the Peace Act 1327, passed in the reign of Edward III, used the phrase "good and lawful men" to be appointed in every county to "guard the peace." Those individuals were first known as conservators or wardens of the peace. The actual title "justice of the peace" only crystallised in 1361, again under Edward III. From that year forward, JPs carried the power to bind over unruly persons "to be of good behaviour," a power that technically remains on the books today.

  The term "magistrate," which became an alternative title for justices of the peace, entered English usage in the 16th century, though the word itself was much older, used centuries earlier to describe officials of Roman law.

  From the Tudor period until the Industrial Revolution, justices of the peace formed the backbone of English local government. Historian Tim Blanning observed that while the Bill of Rights 1689 decisively curbed royal prerogative in Britain, the central government in London could still get its policies implemented in rural areas more effectively than contemporary absolute monarchies such as France could manage. The reason was specific: JPs belonged to the same social class as Members of Parliament, giving them a direct personal interest in seeing laws actually enforced. That shared class interest was the engine, not royal authority alone.

  Being unpaid, the role attracted landed gentry who could afford to serve without a salary. JPs conducted arraignments in all criminal cases, tried misdemeanours and local infractions, regulated wages and food supplies, managed roads, bridges, prisons, and workhouses, and set the County Rate. Towns that could not find unpaid volunteers had to petition the Crown to hire a paid stipendiary magistrate instead. The Municipal Corporations Act 1835 then stripped most municipal corporations of their power to appoint normal JPs, handing that function to the Lord Chancellor.

• 3. Women and the Bench

  ›

  Women were not allowed to become JPs in the United Kingdom until 1919. The first woman to hold the office there was Ada Summers, the Mayor of Stalybridge, who qualified by virtue of her mayoral office. In October 1920, Summers was appointed a JP in her own right, joined in the same appointment by pioneers including Edith Sutton and Miriam Lightowler OBE in Halifax.

  But the United Kingdom was not first in the English-speaking world. Canada made the second appointment of a woman as a magistrate anywhere in the then British Empire; the first was in South Australia a year earlier. Emily Murphy of Edmonton was sworn in as a police magistrate in the Women's Court of the City of Edmonton, Alberta, on the 19th of June 1916, preceding Ada Summers by more than three years.

  In Queensland, Australia, the first woman to become a JP was Matilda (Maud) Hennessey of Mackay, appointed on the 24th of April 1918. South Australia's first women justices were appointed in July 1915, making that state the earliest of all.

  In Victoria, Australia, Mary Catherine Rogers became a JP in 1920, the same year she became the first woman councillor in Australia, elected in the City of Richmond.

  By 2018, about one-third of JPs in England and Wales were women. By 2021, women made up 56% of sitting magistrates there, a reversal of the centuries-long exclusion. As of August 2022, around 3,500 JPs and bail justices served in Victoria alone, collectively signing more than 1.5 million documents and assisting more than 350,000 people each year.

• 4. The American Experience

  ›

  The office of justice of the peace arrived in North America directly from England and became a standard feature of colonial and later state government. In the American colonies, JPs exercised jurisdiction in civil and criminal matters, handled minor disputes, petty offences, and a range of local administrative functions. They issued warrants, administered oaths, performed marriages, and served as the local face of the law.

  Many were lay judges with no legal training, a feature that persisted for centuries. During the 20th century, reformers pushed back against this system, criticising local lay courts as fragmented and inconsistent. Many states replaced JP courts with more centralised lower courts staffed by salaried, law-trained judges.

  Two US Supreme Court cases defined the constitutional limits. In Gordon v. Justice Court in 1974, the Supreme Court of California held that due process was violated when a non-attorney judge presided over a criminal trial that could result in imprisonment, unless the defendant waived that right. Two years later, in North v. Russell (1976), the Supreme Court of the United States held the opposite federal standard: trial before a non-lawyer judge did not violate due process, as long as the defendant had the right to a full trial before a law-trained judge afterward.

  Today, the office survives in varied forms across many states. In Texas, JPs are elected every four years on a partisan ballot and are not required to be attorneys, though they must take 80 hours of state-mandated legal classes in their first year and 20 hours annually thereafter. In Arkansas, the justice of the peace holds no judicial authority at all; instead, Arkansas JPs sit on county quorum courts as something closer to county commissioners, passing budgets and creating ordinances. In Florida, the office was abolished when the state constitution was amended in 1968. In Minnesota, it was abolished in 1977.

• 5. The Honorary Turn

  ›

  In several jurisdictions, the justice of the peace evolved away from judicial work entirely and became a title of honour with administrative functions attached.

  In Hong Kong, the historical judicial functions of JPs were replaced by full-time legally qualified magistrates. Today, the title is given by the government to community leaders and to certain officials during their terms of office. Their duties include visiting prisons, institutions for young offenders and drug addicts, psychiatric hospitals, remand homes, and detention centres. They also monitor the drawing of the Mark Six lottery to ensure fairness, a function that illustrates just how far the role has drifted from its medieval origins.

  Singapore follows a similar model. JPs there are appointed by the President under section 11(1) of the State Courts Act 1970 for renewable five-year terms, chosen from individuals who have made significant contributions to their professions, public service, social services, or the community. They carry no judicial role. Under the Prisons Act 1933, a JP appointed as a Visiting Justice may inspect any Singapore prison at any time. Under the Societies Act 1966, a JP may enter or authorise police entry into any place believed to be the site of an unlawful society meeting and may issue a search warrant or arrest warrant in that context.

  In Malaysia, JPs have largely been replaced by legally qualified stipendiary magistrates in the courts, but state governments continue to appoint them as honorary titles. In 2004, associations of JPs pressed the federal government to allow them to sit as second-class magistrates to help reduce the court backlog, though the outcome was not resolved at the time.

  In India, JPs still exist in law but no longer occupy a prominent role.

• 6. The Modern Volunteer Magistrate

  ›

  England and Wales today rely on trained volunteers who sit in panels, typically three at a time, to handle the bulk of the country's criminal caseload. Magistrates' courts handle over 95% of criminal cases in England, Wales, and Northern Ireland. All criminal cases, even the most serious, begin in the magistrates' court before moving to the Crown Court if needed.

  The selection process is rigorous. A local advisory committee assesses five qualities: awareness of social issues; maturity and understanding; reliability and commitment; understanding of documents and effective communication; and logical thinking. Police officers cannot be appointed due to conflict of interest. All new justices undergo comprehensive training delivered by the Judicial College, mentored by magistrates with at least three years of service. New JPs must sit alongside mentors on at least six occasions during their first eighteen months. They are appraised every four years, or every two years if they serve as a presiding justice, and must complete a minimum of 26 half-day sessions per year.

  The presiding justice, known as the PJ, speaks for the bench in open court and is addressed as "sir," "ma'am," or "your worship." The other two magistrates are called "wingers." All three carry equal authority in the decision-making. Justices are unpaid, though they may claim up to £116.78 a day to cover travel, subsistence, and loss of earnings.

  Cardiff Magistrates' Court holds a unique national responsibility: it is the only court in England and Wales that deals with offences under the Companies Act 2006, such as late filing of accounts or directors' offences. Westminster Magistrates' Court handles terrorism and extradition matters for the whole of the UK, though these cases are typically heard by district judges rather than lay justices.

• 7. Global Variations

  ›

  Belgium uses justices of the peace as the country's small claims courts, sitting at the bottom of the judicial hierarchy. As of 2017, there were 187 judicial cantons in Belgium, each with its own justice of the peace. The justices have original jurisdiction in civil cases where the disputed amount does not exceed 5,000 euros, as well as in landlord-tenant disputes, evictions, easements, consumer credit, unpaid utility bills, legal guardianships for incapacitated seniors, and the involuntary commitment of the mentally ill to psychiatric facilities.

  In Canada, Quebec distinguishes between two types: administrative justices of the peace, who receive criminal informations and issue warrants, and presiding justices of the peace, appointed by the Crown to try some criminal matters. The presiding type is drawn from advocates of at least ten years' standing and serves full-time until the age of 70. Ontario JPs must retire at 65 but may continue working until 75 with the approval of the Chief Justice of the Ontario Court of Justice.

  New Zealand drew up a new law for the role in the Justices of the Peace Act 1957. A separate tier, the Judicial Justice of the Peace, can sit on the bench in District Court for minor criminal cases. Before 2012, all New Zealand JPs could issue search and arrest warrants. The Search and Surveillance Act 2012 moved that power to a separate Issuing Officer role; JPs who want it must apply, complete additional training and exams, and pass a vetting process by the Attorney-General. Appointment as an Issuing Officer runs for a maximum of three years at a time. On the 1st of October 2025, amendments tied to New Zealand's accession to the Budapest Convention on Cybercrime shifted some warrant powers further up to High Court Judges only.

  Tonga authorised its first justices of the peace in 2014. The initial 19 were appointed across several island groups, including Niuatoputapu, Niuafo'ou, Ha'apai, Vava'u, and Tongatapu, with powers to grant bail, issue search warrants and subpoenas, and witness documents. Their term of office is one year, renewable. Sri Lanka traces its JP history to 1801, when the post was introduced during the British colonial era by Governor Frederick North, and today counts around 100,000 JPs across the island.
